General purpose
Swish
This app allows you to make payments by scanning a QR code with your phone : this kind of app is usually useful to pay back a friend but in Sweden it is also used by a huge number of commerces, both physical and virtual.
BankID
This app is not just useful but mandatory. You will use it for everything : logging to your bank account, logging to skatteverket, authorizing payments… For Belgians like me, it is the local equivalent of ItsMe but it is much more ubiquitous.
Wise (previously TransferWise)
I have already mentioned this application in the moving to Sweden post.
Göteborg specific
Parkering
As the name implies this application is used to pay for your parking. It also helps you find a parking place as it also provides a map of the available parkings. You have the option of launching a navigation through Google Maps once you have chosen your parking.
To be able to pay you have to link a credit or a debit card.
Vastraffik
Göteborg has a fantastic public transportation system but it is too much for Google Maps to handle. Enter the Vastraffik app, whose main feature is to allow you to buy tickets but you can also use its ‘reseplanering’ function to guide you towards the most advantageous itinerary that uses your feet and public transport.
For payment you can use Swish or link a card.
